vacationer rescued ‘Jack’ the sea turtle from ‘death’s door’

Clinton Deane just might have saved Jack the sea turtle’s life.

While swimming in the ocean with his kids between 65th Avenue North Friday afternoon, the vacationing Maryland resident noticed a large Loggerhead Sea Turtle floundering as it struggled through the waves.

Believing that the turtle likely wasn’t going to survive the situation, Deane ushered it to shore, where Myrtle Beach fire and police watched over it until members of the South Carolina United Sea Turtle Enthusiasts arrived to take it Charleston.

“It wasn’t going to make it out there, so hopefully it will make it here,” said Deane, whose daughter named the turtle “Jack” following the rescue.

This Whale Tail Took Grand Prize in the Photo Contest

Until last year, photographer Reiko Takahashi was working as a semiconductor engineer, escaping the office a few times a year to pursue her longtime passion for marine life, diving, and underwater photography. Then, in early 2018, a last minute trip to snorkel off the coast of Kumejima Island near Okinawa, Japan, brought the photographer face-to-face with humpback whales for the first time, where she unwittingly captured the image that won grand prize in the 2018 National Geographic Travel Photographer of the Year contest.

“I was really longing to see the bond between a humpback whale and her calf,” Takahashi recalls. Fascinated by the close relationship between whales and their young—and the time they spend together at the beginning of life—Takahaski committed herself to researching the animals. Though she photographed many types of marine life—sharks, manta rays, jackfish, and more—she had yet to swim with humpback whales, a species she longed to see in person. “I became crazy about whales,” she admits.

Secret to whale shark hotspots

A study has uncovered the secret to why endangered whale sharks gather on mass at just a handful of locations around the world.

The new insights into the habits of the world’s largest fish will help inform conservation efforts for this mysterious species, say the researchers.

Large groups of whale sharks congregate at only around 20 locations off the coasts of countries including Australia, Belize, the Maldives and Mexico. Why the sharks, which can reach more than 60 feet in length, choose these specific locations has long perplexed researchers and conservationists.

The new study, by researchers at the University of York in collaboration with the Maldives Whale Shark Research Programme (MWSRP), has found that the shark “aggregation sites” show many common characteristics — they are all in areas of warm, shallow water in close proximity to a sharp sea-floor drop off into deep water.

The researchers suggest that these sites provide the ideal setting for the filter-feeding sharks to search for food in both deep water and the warm shallows, where they can bask near the surface and warm up their huge bodies.

Supervising author of the study, Dr Bryce Stewart from the Environment Department at the University of York, said: “Sharks are ectotherms, which means they depend on external sources of body heat. Because they may dive down to feed at depths of more than 1,900 metres, where the water temperature can be as cold as 4 degrees, they need somewhere close by to rest and get their body temperature back up.

“Steep slopes in the sea bed also cause an upwelling of sea currents that stimulate plankton and small crustaceans such as krill that the whale sharks feed on.”

However, these perfectly contoured locations are not without their drawbacks due to human activity. Sharks swimming in shallow waters close to the surface are vulnerable to boat strikes caused by vessels ranging from large ships to tourist boats hoping to spot them.

Lead author of the paper Joshua Copping, who carried out the research while studying for a masters in Marine Environmental Management at the University of York, and is now working on a PhD at the University of Salford, said: “Individual whale sharks can be identified by their unique pattern of spots and stripes which allows researchers to follow specific sharks that visit these aggregation sites. That means we have a good idea of the rate and extent of injuries at each of these locations and sadly it’s generally quite high.”

Boat strikes, along with accidental trapping in fishing nets, and the targeted hunting of the species for their fins and meat, have contributed to an alarming decrease in global whale shark numbers in the past 75 years.

By highlighting what makes these areas important to the whale shark, the researchers hope this study will also highlight the importance of managing these areas carefully in order to minimise human impact on the shark’s habitat and behaviour.

Dr Stewart added: “The more we know about the biology of whale sharks the more we can protect them and this research may help us to predict where whale sharks might move to as our climate changes.

“Not only do we have an ethical responsibility to conserve this miraculous animal for future generations, but they are also extremely valuable to local people on the coastlines where they gather, which are often in developing countries. While a whale shark can be worth as much as $250,000 USD dead, alive it can provide more than $2 Million USD over the course of its life span.”

Co-author James Hancock from MWSRP added; “Whale sharks can travel huge distances around the globe and the existence of such a small number of known aggregation sites suggested there had to be something about the depth and shape of the underwater terrain in these areas that makes them appealing.

“It’s very exciting to have narrowed down some of the key reasons why whale sharks choose these specific areas. However, the main focus of this research was on costal aggregations which are largely made up of young sharks — exactly where the rest of the demographic hang out is still unclear.”

100 Women: ‘You are truly free while freediving’

Freediving can be a dangerous sport – descending to extreme depths and holding your breath until you resurface.

Yet, according to Egypt’s record-breaking freediver Raghda Ezzeldin, as soon as you go underwater, “you forget about everything”.

Raghda and Aliaa Hassan, who in 2014 became the first Arab woman to compete and break records, explain why free diving is their passion.

Freediving off Hawaii’s big island

Two minutes and 12 seconds.

That’s how long my spearfishing partner had been underwater on one breath. I last saw him descending past 100 feet, toward the 125-foot bottom. I floated on the surface, ostensibly as his safety diver, more realistically just praying that he would ascend out of the abyss. Soon. With each passing second a new and more terrifying scenario ran through my mind. Maybe he shot a fish and got tangled in the reef. Did he pass out on the bottom? What about that shark we saw?

Then, just as I was about to do … something … I caught a glimpse of him rocketing up from the depths. I swam over to meet him as his head burst above the waves. I was relieved he was OK.

Right up until his eyes rolled back in his head and he sank below the surface, dropping his gun.

I grabbed him and pulled his head back above water.

“Kyle! Kyle!” I yelled. His eyes opened and he took a breath.

“I’m good,” he said. But he wasn’t. His lips were blue, he was disoriented and weak. Kyle had experienced a shallow-water blackout. Essentially, he had fainted from hypoxia. On land, you might fall and bump your head. In the ocean, without help, you sink and die. While statistics are elusive since most deaths occur alone, it’s said that shallow-water blackout accounts for more than 99 percent of freediving deaths. Sharks, boat accidents – nothing else comes close.

It’s tragic because it’s so preventable. Just. Don’t. Be. Stupid.

Soon after watching my friend almost die – motivation I would not recommend – I did an uncharacteristically smart thing: I boarded a plane to freediving’s mecca, the west coast of Hawaii’s Big Island, to take a Freediving Instructors International level-one class, a course designed to make a very dangerous sport safe, or at least safer.


I met my FII instructor, Cory Fults, shortly after I landed. A 24-year-old underwater photographer with male supermodel looks and the modesty of a guy who genuinely doesn’t know he looks like a supermodel, Fults — who grew up in Newport Beach before moving to Hawaii to pursue the sport — spends four to six hours in the ocean every day.

Like many other world-class freedivers, Fults moved to Kailua-Kona for the ocean conditions. Because the island is the youngest in the chain, it hasn’t had time to build up many sandy beaches or mature coral reefs. This means the water is very clear and very deep mere yards from shore.

“Plus, the island is so large that it blocks the trade winds, so ocean conditions are smooth and perfect most days of the year,” Fults tells me.

Then there is the abundant sea life; Kona has long been fabled for its world-class sportfishing. So, whether you’re a spearfisherman or just want to swim with large ocean animals like dolphins, whales and sharks, Kona is the place. Most people take up freediving for one of those two reasons, many defecting from scuba: You’re not getting near dolphins or gamefish sounding like a bubble-blowing Darth Vader.

It might seem that freediving is so dangerous because we air-breathing, finless humans are ill-equipped for the ocean. You’d be wrong, says Fults. Freediving is dangerous because most humans are idiots (I’m paraphrasing). One, we do really stupid things like diving alone and pushing our limits. Two, we don’t properly use our natural gifts.

In fact, humans have been freediving since long before the advent of $700 wetsuits and custom-made monofins. There’s evidence of freediving activity dating back 4,500 years, and Greek historians write of freedivers recovering treasure and sneaking behind enemy lines.

The point, says Fults, is that the best equipment humans have for freediving is their own physiology, specifically something called the mammalian diving reflex: When our face is submerged in water, our heart rates slow, blood is diverted from the extremities to our vital organs, and blood vessels constrict. This allows us to dive longer and more safely. It’s how world-record holder Herbert Nitsch was able to dive to 831 feet on a single breath.

“We’re not as good at it as whales or dolphins, but we’re pretty good,” says Fults.

The better part of the next two days are dedicated to attaining and retaining this state, along with learning how to make freediving as safe as possible. That is why world-record freediver and Kona resident Martin Stepanek founded FII. He saw too many needless deaths and contends that when done with proper training, knowledge and safety precautions, freediving can be as safe as surfing, sailing or soccer. I tell Fults that I have received stitches in all three of those endeavors.

There’s an awkward silence. We move on.

After working on diaphragmatic breathing to slow my heart and calm my mind, the proper technique for breaking the surface and a dozen other things I’ve developed horrible habits for, I’m ready (very relative term) to hit the ocean for some line diving – literally diving down and up a line.

We travel a few miles down the coast to Honaunau Bay, a bite out of the coast that’s a favorite among freedivers. So frequented is Honaunau by freedivers, there are three permanent mooring lines at various depths. We swim the 75 yards out to the first one, in 160 feet of water, to tie off our float, then drop a weighted line to 80 feet. The short swim takes a while, though, since we run into dolphins and I spend many awe-inspiring moments diving and swimming with them. The dolphins do laps in the bay, making them easy to get near.

Fults says this has become a problem because they use the bay to sleep, which means turning off half their brain while leaving on the other half to identify predators. The contrast created by the sandy bottom of the bay, one of few on the island, makes it easy for them to spot predators. It also means that tour boats and bozos like me can easily find them for GoPro selfies, disturbing their rest.

“If they can’t rest, it makes them less successful hunters, which could lead to survival issues,” says Fults.

Way to kill a dolphin buzz, bro.

At the line, Fults tells me to remove my mask but keep my snorkel in my mouth, and submerge my face for five minutes while practicing relaxed breathing from my diaphragm. This will trigger the mammalian diving reflex.

After that, I’ll perform a few 33-foot warmup dives. When I freedive at home, my first half-dozen dives are usually deeper than they are long — 24 seconds at 30 feet, etc. — so I know it’s going to take more than two of these to get warmed up. Still, I breathe, descend, wait, return to the surface and flash Fults the OK sign.

I look at my watch. One minute, 21 seconds. Whaaaaat? “That felt like 20 seconds,” I almost scream.

Fults just grins. He’s used to this reaction. “The mammalian reflex, bro. It’s no joke.”

Fults teaches me other ways not to “be an idiot and die.” For instance, he explains that it’s not our lack of oxygen that triggers our urge to breath but a buildup of carbon dioxide. That’s why hyperventilation, which decreases the natural level of CO2, is so dangerous. Sure, you’ll stay underwater longer, but it can delay the urge to breathe until your oxygen level is below the level you need for consciousness. Hello shallow-water blackout, or worse.

You may ask, as I did, “What’s worse than passing out in the ocean with a bunch of weights strapped to your waist?”

“A samba is worse,” says Fults, explaining that’s the nickname for loss of motor control. “Picture a seizure, in the ocean.”

During a blackout, he tells me, your brain does a pretty smart thing: It closes your windpipe so no water can enter. So, until you take your last desperate “terminal breath,” your body prevents water from entering your lungs. But during a samba, that doesn’t happen, and since you can’t control your limbs, you sink, breathe and drown. “It’s another reason that the first rule of freediving is always dive with a partner,” says Fults, for like the 186th time in three days.

In the next 30 minutes I easily hit 66 feet and want to go deeper. But in level one, Fults can’t let me. Safety strikes again.

Two freedivers train by diving down and up a line. Cory Fults, who has descended to 220 feet on a single breath, says training with a partner is essential.


Pulling myself up and down on a line is great and all, but it can get a bit repetitive, so Fults lands me a spot on Wild Hawaii Ocean Adventures’ Snorkeling & Marine Life Experience. WHOA is owned and operated by former Army Ranger and freediving world-record holder Brett LeMaster, who launched WHOA in 2011 with his former Navy SEAL attack boat, Ocean Warrior. I ask him how he got a military attack boat. “To get this boat you have to kill five terrorists, the last one with your bare hands,” he says. A moment later, he cracks a smile. “I bought it from a friend.”

Dubbed the Rolls-Royce of Navy SEAL attack boats, LeMaster’s 11-meter rigid-inflatable boat is built for speed and maneuverability; it can reach 50 miles per hour and turn or stop on a white cap.

LeMaster uses these features to hunt large open-ocean animals — everything from dolphins and pilot whales to false killer whales and large sharks — so guests can swim with them. His is the only tour on the island that does this, so I ask him how he gets away with it when others can’t.

“We ignore our insurance policy.”

About 30 minutes later, that phrase runs through my mind as we slide overboard about a mile offshore in thousands of feet of electric blue water and immediately see two very large oceanic whitetip sharks, a species known to be aggressive. I did my best to get my mammalian reflex to kick in and slow my heart — not easy when a 10-foot shark is deciding whether you are food. But really, it’s an experience like no other. LeMaster limits his tours to eight people, with two in the water at a time, so animals don’t spook and encounters are as natural, and as close, as possible.

In the next hour we swim with (awake) dolphins, short-finned pilot whales – “The males can get protective, so stay alert,” says Fults – and finally move into Kealakekua Bay for a reef snorkel.

On the boat ride in, everyone smiling and calm after their ocean encounter, LeMaster decides it’s a good time for some “speed work” to show just what an ex-Navy SEAL attack boat can do. LeMaster makes the “grippy grippy” sign (a clenched fist in the air) and puts the hammer down on the 940-hp jet engines below our feet. The SEAL boat leaps into action as if armed combatants have just invaded Kona. LeMaster steers directly — directly — at the cliffs in a move that I’m certain is expressly forbidden by his insurance policy. We close on the cliffs, each of our fun, excited, wow-this-thing-is-fast Disneyland grips rapidly turning to this-maniac-is-trying-to-kill-us death grips.

About the time we are all thinking, “Do I have time to abandon ship before we smash into that cliff face?” LeMaster throws the helm to port and we seemingly bank off the cliff at 50 mph, close enough to see crabs fleeing into cracks.

LeMaster looks back and smiles – or checks to see whether we’re still there. I’m not quite sure which. I do see why LeMaster does this on the way in, however – my heart rate won’t be under 100 until Christmas, and if I got in the ocean right now I’d have a breath hold of two seconds. LeMaster performs a few more of his “speed work” maneuvers while Fults tells us about the history of the cliff faces we nearly smash into (Honestly, Cory, no one is listening).

Soon we are back at the harbor and LeMaster has skirted another massive wrongful death suit, given seven visitors a lifetime of cocktail chatter and helped convince me that, relatively speaking, maybe freediving isn’t so dangerous after all.

Mission accomplished?
